    We propose a fractal image generation method for data hiding using chaos theory. Chaos is an unpredictable behavior which arises on the dynamical system in turns explains the non-linearity and randomness. The initial condition acts as a key which is generated by the PRNG. The fractal image...

    In decision diagrams (DDs) methods for circuit synthesis, it is possible to directly transfer a DD for a given function f into a network realizing f by the replacement of non-terminal nodes in the DD with the corresponding circuit modules. The chief bottleneck of mapping a DD into a network is...

    For all non-negative integer n and real constants a, b, p and q, the generalized Fibonacci sequence { Un } is defined by Un+2 = pUn+1 + qUn with the initial values U0 = a and U1 = b. Throughout the paper, we study some properties of the generalized Fibonacci sequence. Our results will motivate...

    The main purpose of this paper is to introduce the new sequence spaces c0(F), c(F) and l∞ (F) based on the newly defined regular matrix F of Fibonacci numbers. We study some basic topological and algebraic properties of these spaces. Also we investigate the relations related to these spaces.
